PACKING.

SPECIFICATION forming part of Letters Patent No. 794,892, dated July 18 1905.

Application filed June 4,1904. Serial No. 211,097.

To all whom, it may concern:

Be it known that I, ADoLPH B. SCHIER, a citizen of the United States, and aresident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Packing; and I do hereby declare that the followingis afull, clear, and exact description thereof.

My invention has for its object to provide simple, economical, and effective packing for joints of various kinds, especially those of fruit-jars and their caps, said invention consisting in what is hereinafter particularly set forth with reference to the accompanying drawings and subsequently claimed.

Figure 1 of the drawings represents a sectional view of a fragment of a sealed fruitjar and illustrates the application of one form of packing in accordance with my invention; Fig. 2, a plan View of the packing shown in the view aforesaid, and Figs. 3 and A sectional views of fragments of other forms of packing within the scope of my invention.

Referring by letter to the drawings, A indicates a fragment of an ordinary screw-neck fruitjar, and B a partly glass-lined metal screw-cap in place on the jar-neck. Seated on the rim of the jar in opposition to the lining 5 of the cap is a packing in accordance with my invention. This packing consists of a plate C in the form of a disk and a band D, of elastic compressible material, stretched on the plate to envelop its edge and lap the sides of the same. The plate may be flat; but it is preferably dished and upwardly beaded, as best shown in Fig. 1, the band D being stretched on the horizontal portion of said plate outward from the bead. Rubber of good quality is the preferred material for said band. The packing as a whole serves as'a closure for the jar independent of the cap B, and the pressure of said cap is exerted directly upon the bead d of the plate C, on

which it slips when being tightened.

Hot fruit being put into the jar and packing of the form above specified placed in position, the vacuum in said jar, resulting from cooling of its contents, will operate to draw said packing tight on its seat previous to placing of the cap, by which permanency of the seal is efiected. Hence immediate use of the cap after filling of the jar is not necessary to insure preservation of the fruit, and,said packing serving as a closure, the contents of said jar cannot get in between it and the cap-wall to make the removal of said cap diflicult because of sticking.

In Fig. SI show the plate or holder C having the horizontal portion thereof outward from its bead (2 turned down to formaflange e, and the band D, of elastic compressible material, is laid within the confines of the flange. In .Fig. 4 I show the plate or holder in the form of a washer G, having the band D stretched thereon.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is i l. A packing consisting of a holder in the form-of a plate, and a band of elastic compressible material stretched on the plate to inclose its edge and lap its sides.

2. A packing consisting of a holder in the form of a dished and upwardly-beaded plate. having a flat portion outward from the bead, and a band of elastic compressible material stretched on said fiat portion of the plate to inclose the edge and lap the sides of said plate.

3. A fruit-jar packing consisting of aholder in the form of a dished and upwardly-beaded plate that is horizontal outward from the bead,
